Want to know:
Two experimental runs are performed to determine the calorimetric properties of an alcohol that has a melting point of −10℃. In the first run, a 200-g cube of frozen alcohol, at the melting point, is added to 300 g of water at 20℃ in a styrofoam container. When thermal equilibrium is reached, the alcohol-water solution is at a temperature of 5.0℃. In the second run, an identical cube of alcohol is added to 500 g of water at 20℃ and the temperature at thermal equilibrium is 10℃. The specific heat of water is 4190 J/kg⋅K. Assume that no heat is exchanged with the styrofoam container and with the surroundings. The specific heat of the alcohol is closest to
